Put us to the test

Our Test Labs compare features and prices on a range of products. Try Which? to unlock our reviews. You'll instantly be able to compare our test scores, so you can make sure you don't get stuck with a Don't Buy.

We've quizzed more than 12,000 Which? members on everything from queues to value for money to uncover the nation's favourite supermarket for 2019.

The UK's definitive supermarket survey reveals the best grocery stores and websites, as well as those you might want to avoid.

Supermarkets compete fiercely for customers, and it's getting harder than ever to know which ones have the best deals, offer great-quality food, and give you five-star service to boot.

We asked more than 12,000 supermarket shoppers to tell us what they really think of their supermarket, so we can tell you which are the best – and the worst.

We've rated all of the major supermarkets, from giants such as Tesco and Sainsbury's to discounters Aldi and Lidl. We've also assessed online-only grocer Ocado, and online supermarket services such as Iceland online and Waitrose online, to see which will bring you the freshest produce, and offer convenient delivery slots with stellar driver service.

Only logged-in Which? members can view our exclusive scores and ratings in the tables below. Once logged in, you can find out which supermarkets received the highest customer score and which were rated best for value for money, store appearance and other factors. 

The ratings are based on our survey of 12,170 Which? members about their supermarket shopping in October and November 2018.

You can also discover which own-label products we rate as Best Buys.
